[xml/sgml-pkgs] Bug#271754: libxslt1.1: date:add-duration() bugginess

[Sal Paradise]

Subject: libxslt1.1: date:add-duration() bugginess

Package: libxslt1.1

Version: 1.1.8-4

Severity: normal



The EXSLT function date:add-duration() produces bad values on some

inputs described here.  Apply the following stylesheet to any XML

document (the XML input is ignored) using xsltproc to reproduce.



<?xml version="1.0" encoding="utf-8"?>

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

  xmlns:date="http://exslt.org/dates-and-times" version="1.0">



  <xsl:output method="text"/>



<xsl:variable name="nl">

<xsl:text>

</xsl:text>

</xsl:variable>



  <xsl:template match="/">

    <xsl:variable name="myduration1" select="'-P28DT23H55M8S'"/>

    <xsl:variable name="myduration2" select="'-P1DT12H54M59S'"/>

    <xsl:value-of select="date:add-duration($myduration1, $myduration2)"/>

    <xsl:value-of select="$nl"/>

  </xsl:template>



</xsl:stylesheet>



The buggy output from libxslt1.1 is:

-P31DT11H9M53S



The correct output should be:

-P30DT12H50M7S
